Methods, apparatuses, and storage media associated with compaction of data from one or more computing devices are disclosed. In various embodiments, one or more Internet of Things (IoT) devices may transmit information to a computing system. The computing system may group together raw data received from these one or more IoT devices based on a shared attribute. The computing system may select a compaction scheme to represent the knowledge conveyed by a group of the raw data. The computing system may apply this compaction scheme to the group of raw data to generate data that is representative of the group of raw data. Other embodiments may be disclosed or claimed.
